After setting up the G540 yesterday I was playing with the motor tuning......
Here is the setup as it sits.
Minitech Minimill2 1/2-10 tpi precision acme lead screws, xylotex 269 OZ steppers (2.8A) G540 driver and a 24V power supply.
I had the power supply from my first Xylotex kit that took a swan dive on me a year ago. Also for the resistors, I needed 2.8K but the local rat shack only had 2.2K So I am severely under powered by the limit resistors and the low voltage PSU.
Here is a short video I took of it running a test toolpath.
